The present invention relates to a motorized fumigation system designed to promote the control of agricultural and urban pests in open spaces, more particularly among the systems that can carry out the fumigation process by creating a hot or a cold mist, and more specifically due the fact of both processes of the mist creation could be integrated into one light weight vehicle. The system of the present invention consists of three subsystems: a first subsystem designed to storage and pumping (S1); a second subsystem designed to hot fumigation (S2); and a third subsystem designed to cold fumigation (S3).
